What Omsula is and what it is used for

The active ingredient in Omsula is tamsulosin. This is a selective alpha1A/1D-adrenoceptor
antagonist. It reduces tension of the smooth muscles in the prostate and the urethra, enabling urine to
pass more readily through the urethra and facilitating urination.
Omsula is used to treat the symptoms of an enlarged prostate - a condition technically known as
benign prostatic hyperplasia or BPH. If the gland becomes enlarged, it can squeeze the urethra,
interfering with the flow of urine. This can cause difficulty in starting urination, a weak flow of urine,
and the need to urinate urgently or more frequently. Omsula doesn't shrink the prostate. Instead, it
relaxes the muscle around it, freeing the flow of urine and decreasing urinary symptoms.

What you need to know before you take Omsula

Do not take Omsula
If you are allergic to tamsulosin hydrochloride or any of the other ingredients of this medicine
(listed in section 6).

Warnings and precautions

Before starting treatment you should tell your doctor if you are suffering from any other disease,
particularly from kidney and liver disorders, heart and circulatory system diseases.
Rarely, fainting can occur during the use of Omsula, as with other medicinal products of this
type. At the first signs of dizziness or weakness you should sit or lie down until they have
Periodic medical examinations are necessary to monitor the development of the condition you
are being treated for.



If you are undergoing eye surgery because of cloudiness of the lens (cataract) or increased
pressure in the eye (glaucoma), please inform your eye specialist that you are using or have
previously used Omsula. This is because Omsula may cause complications during the surgery.
The specialist can then take appropriate precautions with respect to medication and surgical
techniques to be used. Ask your doctor whether or not you should postpone or temporarily stop
taking this medicine when undergoing eye surgery because of a cloudy lens (cataract) or
increased pressure in the eye (glaucoma).

Children and adolescents
Do not give this medicine to children or adolescent under 18 years because it does not work in this
Other medicines and Omsula
Tell your doctor or pharmacist if you are taking, have recently taken or might take any other
This is because Omsula can affect the way that some other medicines work and some other medicines
can affect the way that Omsula works.
In particular tell your doctor or pharmacist if you are taking:

Medicines to lower your blood pressure such as verapamil or diltiazem

Medicines to treat a fungal infection such as ketoconazole or itraconazole

Other alpha blockers such as doxazosin, indoramin, prazosin or alfuzosin

Erythromycin, an antibiotic used to treat infections
Please inform your doctor or dentist that you are on Omsula before any operation or dental procedure
as there is a potential that your medicine may interfere with the effects of the anaesthetic.
You should only take medicines concomitantly with Omsula if your doctor allows it.
Pregnancy, breast-feeding and fertility
Omsula is not indicated for use in women.
In men, abnormal ejaculation has been reported (ejaculation disorder). This means that the semen does
not leave the body via the urethra, but instead goes into the bladder (retrograde ejaculation) or the
ejaculation volume is reduced or absent (ejaculation failure). This phenomenon is harmless.
Driving and using machines
No data is available whether Omsula adversely affects the ability to drive or operate machines.
However it should be taken into account that in some patients drowsiness, blurred vision, dizziness
and transient loss of conciousness (syncope) may occur.

How to take Omsula

Always take this medicine exactly as your doctor has told you. Check with your doctor or pharmacist
if you are not sure.
If it is not prescribed otherwise by your doctor the recommended dose is one capsule daily, to be taken
after breakfast or the first meal of the day.
Do not crunch or chew the capsule, swallow it whole.
If you take more Omsula than you should
Contact your doctor immediately or visit the emergency department of the nearest hospital as the
consequences of accidental or deliberate overdose may require medical intervention.
If you forget to take Omsula


Take the forgotten capsule on the same day. However, on the next day do not take a double dose to
make up for a forgotten dose; just resume treatment at one capsule a day.
If you stop taking Omsula
You should not stop taking it without consulting your doctor before.
If you have any further questions on the use of this medicine, ask your doctor or pharmacist.

Possible side effects

Like all medicines, this medicine can cause side effects, although not everybody gets them. Do not be
alarmed by this list of possible side effects, you may not have any of them. Most patients do not notice
any side effects. However if you do and they bother you, talk to your doctor.
If you begin to feel light-headed or dizzy, sit or lie down until you feel better.
Common (may affect up to 1 in 10 people):

abnormal ejaculation (ejaculation disorder). This means that semen does not leave the body via
the urethra, but instead goes into the bladder (retrograde ejaculation) or the ejaculation volume
is reduced or absent (ejaculation failure). This phenomenon is harmless.

If you are undergoing eye surgery because of cloudiness of the lens (cataract) or increased pressure in
the eye (glaucoma) and are already taking or have previously taken tamsulosin hydrochloride, the
pupil may dilate poorly and the iris (the coloured circular part of the eye) may become floppy during
the procedure (see also section 2 “Warnings and precautions”).
In addition to the adverse events listed above, very rapid uncoordinated contractions of the heart,
abnormal heart rhythm, abnormally rapid heartbeat and shortness of breath have been reported in
association with Omsula use. Because these spontaneously reported events are from the worldwide
post-marketing experience, the frequency of events and the role of Omsula in their causation cannot be
reliably determined.

not listed in this leaflet. You can also report side effects directly via Yellow Card Scheme. Website: By reporting side effects you can help provide more information on the
